Kimi no “Hajimete” wo Zenbu Choudai

Saki's loved making bets ever since she was kid. Today's contest was over archery, a sport she excels in. A new student named Sugito is introduced in class and for whatever reason, he seems to know her. Later that day, on her way home from school, Saki is at a loss when she's asked out by a friend from class. Just then, Sugito appears, pulls her close, and out of nowhere kisses her. It can't be... It was her first... But without time to recompose herself, Sugito confesses how he's missed her... and that he's won the bet. Just who is he? (Source : Renta)
